对纤用亚麻（阿里安）与北达科他州油用亚麻茎进行酶法脱胶实验。脱胶酶制剂含Viscozyme L（富含果胶酶的成品酶）和乙二胺四乙酸（螯合剂EDTA）。碾压破裂后的亚麻茎浸吸不同比例的Viscozyme L-EDTA溶液，脱胶后纤维进行梳纺。供测纱样为Shirley机清理的原亚麻纤维与棉花纤维按不同比例混纺而成的纱。处理不同，清理后的纤维性质有所不同。不同配比的酶溶液脱胶后的纤维性质不同，不考虑EDTA的因素，0.3％（v／v）的酶浓度比0.05％的酶浓度脱胶效果好，但纤维强力低。麻样与酶制剂不同，混纺纱的质量变异系数、单纱强力与粒结数存在差异。以成本、纤维和纱的质量为依据，本实验结果确立了脱胶酶制剂的组分含量范围，可作为进一步研究优化亚麻脱胶酶制剂的基础。本实验中，0.3％（v／v）Viscozyme L与25mMEDTA配制的酶溶液脱胶制成的纱最好。因此，可以此为基础进一步研究开发工业级纺织用亚麻短纤维。 相似文献

Coconut fibres were subjected to chemical treatment to obtain softer and finer fibres, suitable to blend with other finer fibre like jute. The chemical softening recipe was optimized using Box-Behnken design of experiments as 40 % Na2S, 10 % NaOH and 6 % Na2CO3, which notably reduced the fineness (33 %) and flexural rigidity (74 %) and improved tensile property of coconut fibre. Effect of softening of coconut fibre on its process performance was studied in high speed mechanized spinning system at different blend ratios with jute. Blending with jute assists in spinning of coconut fibre to produce yarn of 520 tex at production rate of 5-6 kg/h, as compared to 15 kg/day for hand spun 5300 tex raw coconut fibre yarn in manual system. Analysis of blended yarn structure in terms of packing density, radial distribution of fiber components (SEM) and mass irregularity were investigated. SEM shows yarns made from softened coconut fibre -jute blends are more compact than raw coconut fibre -jute blend yarns. Coconut fibres were preferentially migrated to core of the yarn. Major yarn properties viz., tensile strength, and flexural rigidity of raw and chemically softened blended yarns were compared against their finest possible 100 % coconut fibre yarn properties. Yarn made up to 50:50 chemically softened coconut fibre-jute blend showed much better spinning performance, and having superior property in terms of reduced diameter, higher compactness, strength, initial modulus and less flexural rigidity than 100 % raw, 100 % chemically softened coconut fibre rope, and raw coconut fibre-jute blend yarns. 相似文献

Microorganisms can lead to functional, hygienic and aesthetic (e.g. deterioration, staining) problems on textile products.
Natural fibers especially cotton are more easily affected by microorganisms. Blending of cotton fibers with antimicrobial
fibers can enhance the protective properties of products against microorganisms. Demand of antimicrobial performance from
the products changes depending on the application area. Therefore determination of suitable antimicrobial fiber quantity for
the desired application is important. In this study the spinning performance of SeaCell Active/cotton blended open end rotor
yarns and antibacterial activities of fabrics produced by these blended yarns were investigated. Five different cotton/SeaCell
Active blended slivers with SeaCell Active content from 3 % up to 53 % were prepared on drawframe machine and all slivers
were spun into yarns on open end rotor spinning machine at a yarn count of 20 tex with αTt=3827 twist coefficient. The effects of rotor speed, opening roller speed, rotor, opening roller and navel type on the quality
parameters of SeaCell Active/cotton blended yarns were investigated. Tensile properties, hairiness, unevenness and IPI values
of the yarns were reported. All types of cotton/SeaCell Active blended yarns were knitted on a circular knitting machine.
Antibacterial activity of the fabrics was analyzed quantitatively. Antibacterial tests showed that good antibacterial activity
can be achieved after several washings even with 3 % of SeaCell Active fibers in fabrics. 相似文献

Bidirectional PP/jute yarn eco-composites were fabricated via environment friendly commingling technique and its long term durability/life time was monitored as an effect of accelerated solar ageing on its mechanical properties (tensile & flexural). Accelerated solar ageing promoted the thermal oxidation of PP thus resulting in deterioration of its properties, however; MAPP and KMnO4 treated commingled composites showed much better stability towards thermal oxidation brought about by the solar concentrator, compared to untreated sample and neat polypropylene. This increased resistivity of treated composites (especially MAPP and KMnO4) towards thermal oxidation brought about by the solar concentrator is due to the increased interfacial adhesion between the matrix and jute yarn owing to chemical modifications. The significance of effective stress transfer between the PP matrix and reinforcing jute yarns is evident from the increased tear resistance of PP/jute yarn commingled composites with increasing fibre content and also with different chemical treatments. 相似文献

From early times, jute fibre has been generally conditioned for easy spinning by adding oil and water in the form of an emulsion. The commonly used oil consists of C12–C31 fractions of mineral oil that sometimes impart different intensities of oily (kerosene) or fishy smell to the end product. In the present work, efforts have been made to find a suitable sustainable substitute of mineral oil based conditioning agent for spinning of jute yarn and for this, three types of vegetable oil (rice bran oil, palmolein oil and castor oil), a silicone emulsion, a mixed enzyme system and glycerine have been used separately or in combinations as conditioning agents for jute fibre before its mechanical processing for making yarn in jute spinning machines. Considering comparable mechanical process performance for spinning of jute fibre (viz., fibre loss as droppings during processing, moisture retention prior to spinning stage and spinning end breakage rate), tensile properties of yarn, and lower yarn hairiness, it may be suggested to use 2.5% castor oil alone, or 2% castor oil in combination with 0.1–0.5% glycerine in the form of oil-in-water emulsion as the most suitable alternatives to conventional mineral oil-based jute conditioning agent to spin ordinary jute yarn. 相似文献

In this work, the effect of optimum drafting condition on the drafting behavior and yarn quality of the bamboo charcoal-modified
fiber blended spun yarns were studied. We measured the drafting force and drafting force variance, CV% of the bamboo charcoal-modified
Polyester/Cotton (BCP/C) blended roving and bamboo charcoal-modified Rayon/Cotton (BCR/C) blended roving to examine the influence
of the roller gauge and drafting ratio on drafting behavior and yarn quality. We understand that the drafting force of the
bamboo charcoal-modified fiber blended roving follow the same trend as that for the regular P/C and R/C blend roving. However,
the drafting force presents some difference in characteristics between these bamboo charcoal-modified fiber blended rovings.
To correlate the drafting force variation, CV% and the bamboo charcoal-modified fiber blended spun yarn properties, we evaluated
the yarn quality and investigate the yarn quality index in conjunction with the break drafting ratio. Therefore, in this work,
we can obtain the best optimum drafting conditions for bamboo charcoal-modified fiber blended spun yarns; for the 19.7 tex
of BCP70/C30 blend spun yarn was under the roller gauge of 54 mm at the draft ratio of 1.3, whereas, for the 19.7 tex of BCR40/C60
blend spun yarn was under the roller gauge of 54 mm at the draft ratio of 1.2. 相似文献

This paper presents the low stress mechanical properties of plain fabrics woven from cotton, bamboo viscose and cotton-bamboo viscose blended yarns. Three blends (100 % cotton, 50:50 cotton-bamboo and 100 % bamboo) were used to produce three yarn counts (20, 25 and 30 Ne). Each of these yarns was used to make fabrics with different pick densities (50, 60 and 70 picks per inch). It was found that bending rigidity, bending hysteresis, shear rigidity, shear hysteresis and compressibility is lower for bamboo fabrics as compared to those of 100 % cotton fabrics. On the other hand, extensibility, tensile energy and compressional resilience are higher for 100 % bamboo fabrics than 100 % cotton fabrics. Higher pick density increases linearity of load-elongation curve, bending rigidity, shear rigidity and compressional resilience. Shear and bending rigidities show very good correlation with the respective hysteresis values. 相似文献

In the field of yarn spinning engineering, the importance of the processing parameters taken depends directly on the quality
characteristics of the yarn. This study aimed to find the optimal processing parameters for an open-end rotor spinning frame
at work to identify its multiple quality characteristics for yarn. In this study, Bamboo charcoal and cotton 70 %/polyester
30 % (CVC) blended fibers were adopted as the materials, and the open-end rotor spinning frame was used to spin the yarn.
In order to identify optimal conditions of an open-end rotor spinning frame, the Taguchi experimental method was applied to
design open-end rotor spinning experiments, and the L9 orthogonal array was chosen in accordance with nine sets of experiments and contained four control factors and three levels.
Furthermore, a response surface methodology (RSM) was used to obtain the models of significant processing parameters for the
strength, unevenness, I.P.I, and hairiness. Based on experiments designed to obtain an open-end rotor spun yarn Ne 30, the
strength, unevenness, imperfection indicator/km (I.P.I) and hairiness were then chosen as the quality characteristics. In
addition, grey relational analysis integrated the optimal processing parameter of multiple quality characteristics, and a
confirmation experiment was performed. In conclusion, the optimal processing parameters under steady spinning conditions were
a rotor speed of 88000 rpm, a feed speed of 0.392 m/min, and a winding speed of 39.466 m/min. 相似文献
